Interstellar dust is ubiquitous in the interstellar medium (ISM) and it is
involved into the physical, chemical, and dynamical evolution of numerous environments through different processes such as the gas heating through the photoelectric effect [1]}, [2]} and the H\(_2\)  formation on dust surfaces [3]}, [4]}, [5]}. The efficiency
of these processes depends crucially on the dust properties (size, composition, and shape). It is
therefore crucial to constrain those properties in order to understand better
the different environments where dust exists. However, the broad disparity in
the physical conditions (density and irradiation) triggers an evolution of these dust properties through grain growth (i.e. accretion and coagulation), grain destruction (i.e. photo-destruction and collisions), and processing (i.e. aromatisation, dehydrogenation), which are not yet fully understood.
